What do you consider "Fast" or "Slow"? The receivers we built had
seven different AGC time constants, up to 10 seconds.

Michael, what receivers were these and why such incredibly fast AGC?
I assume these are release speeds; what were the corresponding attack
speeds?

Microdyne 700 series, and other lines like their 1100, 1400 and 2800
series. They were telemetry systems, and they were typically used in
diversity mode so you needed the fast AGC for some applications. They
had matching integration times for attack and release. I should know, I
tested hundreds of the boards on the bench while using a time interval
counter and calculating the reciprocals on the slower ranges.
